This is a complicated area. As a member in an LLC taxed as a partnership, you have 3 loss limitations that determine the allowable annual loss; basis, at-risk, and passive activity (in that order).
Based on your limited facts, you appear to know your basis in the LLC investment. Additionally, you indicate that losses have been suspended as a result of the passive activity loss rules.
If you go through the detailed input questions and indicate that you have a full disposition of the interest, TT should handle this correctly. This happens all the time.
You have to keep in mind that there is a circular process between the loss you may be looking for and the reporting of any suspended losses which would be taken as an ordinary loss at this juncture.
Also keep in mind, that even though losses are suspended due to the passive activity rules, these losses still reduce your basis immediately.
Depending on the $$ involved, you may want to consider getting some professional help in understanding what the end result should be.
